Abstract
Lipids containing gamma-linolenic acid are extracted from cells of Mortierella genus fungi by first grinding the cells in the presence or absence of a hot alcoholic solvent, and then extracting the alcohol-treated ground cells with a solvent in a supercritical state, or a mixture of a solvent in a supercritical state with a lower aliphatic alcohol or a lower aliphatic hydrocarbon.
